Abstract

The embodiment of the invention provides a data writing method and device and a data reading method and device. According to the embodiment, a data writing process and a data reading process are included; after a Hash value of written data is recorded, the written data is encrypted and stored; and in the data reading process, corresponding data cannot be read unless a Hash value of a reading request key is matched with a Hash value of to-be-read data. Compared with the prior art, it is allowed to save the Hash value of the written data only, a request key of the written data does not need to be saved, different keys can be used for different data, and therefore data access speed can be considered on the premise of guaranteeing data access security.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of the Internet, in particular to a data writing method and device, and a data reading method and device. [0003] 【Background technique】 [0004] With the advent of the era of big data, the amount of data continues to increase, and the number of database visits also continues to increase, and users have higher and higher requirements for data access speed. Usually, in order to improve the data access speed, it is necessary to write the data to be accessed into the memory of the data server, and then access it. However, data access security cannot be ignored. At present, access security is usually achieved by encrypting written data through software, but this will reduce the speed of data reading. [0005] Therefore, in the face of the contradiction between data access speed and data access security, how to adopt reasonable data writing and data reading methods is an urgent problem to be solved by t...
